HENRY O. MILLER, OF WATERFORD, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 793,010, dated June 20, 1905.

Application filed February 8, 1904. Serial No. 192,518.

To all whom, nan/y concern:

Be it known that I, HENRY O. MILLER, a citi zen of the United States, residing at \Vaterford, in the county of Saratoga and State of New York, haveinvented new and useful Improvements in Machines for Locating and Stitching Buttonholes in Collars. Cuffs, &c., of which, the following is a specification.

This invention relates to a machine for locating buttonholes in collars, code, 820.

The'object f the invention is to provide mechanism for adjusting a pair of butto nholesewing machines to operate upon collars of different sizes and styles, in combination with a centralizing mechanism consisting of a movable platform which receives the collar and delivers the same to the sewing-machine to accurately locate the end buttonholes an equidistance from a determinate point in the collar.

The invention also comprehends improvements in the centralizing mechanism which consists of a platform on which the collars are placed to be gaged, the collars then being moved to the sewing-machines. The platform carries adjustable devices with adjacent appropriate scales for assisting the operator in adjusting the machine for collars of different sizes and styles. In order that time may be saved, the various parts are arranged with a view of permitting the centralizing meehan ism being withdrawn from the sewing-machines while the latter operate upon the collar previously delivered thereto to enable the operator to centralize another collar and have it ready for the successive operation of said sewing-machines.

Other objects and advantages will be hereinafter referred to and be particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of the machine. Fig. 2 is a front view of the same. Fig. 3 is a section taken at line 1 in Fig. 1, showing the collar in place beneath the needle. Fig. 4 is a section taken at same line in Fig. 1, showing the first collar in place under the needle and the mechanism for cen tralizing collars drawn toward the operator for placement of a second collar. Fig. 5 is an enlarged plan view of one of the temporary collar-holders. .Fig. 6 is a plan view of the same mounted on the platform. Fig. 7 is a section on the line 2 2, Fig. 6. Fig. 8 is a section on the line 3 3, Fig. 6. Fig. 9 is a section on line 1 4, Fig. 6. Fig. 10 is a section on the line 5 5, Fig. 3. Fig. 11 is a section on the line 6 6, Fig. 3. Fig. 12 is a detail enlarged view of a part shown in Fig. 11. Fig; 13 is a section on the line 7 7 of Fig. 12. Fig. 1 is a view similar to Fig. 12 with the buttonhole engaging device turned transversely. Fig. 15 is a planview of a different form of my invention for use in connection with collars or cuffs without end tabs. Fig. 16 is a detail plan view of atemporary holder for use with a collar or cuff without end tabs. Fig. 17 is an edge view of the same.

In the drawings, A represents the bed of the machine formed with ways to accommodate blocl: B B, carrying swiveling plates 0 O, and on each plate is mounted a buttonholesewing machine D. A rod D having right and left hand screw-threads, passes through the nuts D on the blocks to simultaneously adjust the buttonhole-machines toward or from each other. ScalesM M are formed adjacent the blocks B B, and on the latter are circular scales N N.

The above-mentioned parts specifically form no part of my present invention, being described and claimed in a pending application, Serial No. 103,742, filed April 19, 1902.

A barF is fastened to the bed approximately midway between the sewing-machines, and formed in the upper side of said bar is a dovetailed groove 6, in which fits a rib formed on the base-plate F of a carriage G. The baseplate F is provided with standards F F, supporting a platform F which carries my improved centralizing mechanism. A scale Q, is located adjacent the dovetail groove,-and a pointer g on the base-plate F registers with the scale to determine-the adjustment of the carriage with reference to the sewing-machines and the style of collar. The carriage is limited in its movement by a headed rod F which is threaded in a lug on the bar E and held in locked position by a set-nut f The rod passes freely through an opening f,formed in a lug F on base F, and nuts f engaging the threads of the rod, serve as a stop. The

carriage is limited in its outward movement by the head of the rod and in its inward movement by the nuts the latter being previously adjusted.

A lever H is pivotally connected to the standards F by a pin It, the arm Z of the lever being at an angle to the rear arm A and is provided with a handle H. The arm'h is formed with a slot It, in" which is adjustably mounted .a centralizing engaging device I. A spring H is connected at one end to the arm 7t and at its opposite end to a threaded screw g passing through a lug g and adjusted by a nut g. The tension of the spring tends to throw the arm 7 up toward the platform F it's upward movement being limited by a stop it.

' The centralizing engaging device I is adjustable in the slot formed in arm b and it consists of a holder I, having a square body portion d, flanged at its upper end i, and a screw-threaded stem a, which is engaged by a binding-nut '5 The adjustment of the device I is essential to adapt-the machine for various sizes and styles of collars, and to op- .erate upon collars having the central button:

holes transverse of their length the blade will be turned accordingly, as shown in Fig. 12. A transverse plateJ is carried by the platform F and it is provided each side the platform with a slot j, and adjacent each slot is a scale 0. A block K, having flanges which engage the under side of plate J, tits in each slot j, and on the top of plate J is a collarsupporting plate L, carrying a gage-bar. K, and a set-screw k binds the gage-bar, collarsupporting plate L, and plate J together. A pin is also engages the parts to prevent lateral displacement after they have been adjusted. The collar-supporting plate is fur- .ther provided with set-screws j to engage the block K to assist in maintainingthe parts in their relative location. The collar-supporting plates extend beyond the plate J, that their rear ends may be passed beneath the clothclamping plates of each machine and adapted to support the end portions of a collar in which a buttonhole is to be formed.

Each gage-bar K is formed with a series of openings 70, with an adjacent scale P, the setscrew F, and pin k',engaging two of the openings when setting the gage-bar for a difierent shape or style of collar. The inner end of .the bar K is formed with a series of angular serrations Z gage-pin Z, and a spring-finger Z, the latter being so located as to overhang and slightly contact with the serrations to temporarily hold the end of a collar or cufi.

Adjustably secured by a rivet 7 and block R in slots 1' are supplemental holdingdevices R, designed to exert pressure on the plate J and a collar or other article on the same. The holding devices may be turned on their pivots to serve as supports for a portion of an article being operated upon in case the latter shouldbe unusually wide or long.

793,010 BEST AVAILABLE COP In operation the various adjustments are made inaccordance with a card-schedule having scales corresponding with the various scales on the machine for each style and length of collar when the machine is ready for forming buttonholes. The carriage is first withdrawn, as shown in dotted lines in Fig. 1, and the blade I is slipped through the center buttonhole, (or the collar is engaged by a point if no center buttonhole has been formed.) The tabs Z of collar Z are then slipped under the temporary holding devices l until the corners .2 engage the gage-pins l, as shown in Fig. v5. These pins are exactly the same distance each side a point in the collar where a buttonhole is to be formed. The collar havin g been accurately gaged, thev operator grasps handle H and forces the carriage toward the sewing-machines until lug F strikes nut f which properly presents the collar under the work-clamps, and as the collar-supports project beyond the path of the needle they draw suflicient thread for the next operation. The cloth-clamps are now released to holdthe collar, and the operator rocks the handle in the direction of arrow 3, Fig. 3, which disengages the blade I from, the buttonhole, and by a continued pull on said handle the carriage is withdrawn to reload it for the next operation, the sewing mechanisms being started in the meantime to form the buttonholes. When the carriage is withdrawn, the temporary holding devices readily release the ends of the collar, as will be obvious. buttonholes are finished the operator has had ample time to place another collar on the plat form and the clamps are raised for the removal of the article operated upon.

When tabless collars or cuffs are to be operated upon, two gage pins Z Z are employed; as shown in Fig. 16.
